Barbara Lynette Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a '' Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating '' Darwinia capitellata'' from a more widel ...

Donnelly River (Western Australia)
The Donnelly River is a river in the South West of Western Australia. Its main tributaries are Barlee Brook and Carey Brook. The river runs primarily through state forest reserves, although 25 private landholdings are situated along the length of the river. Clearing of the catchment area is estimated at 20% with the land mostly being used for viticulture, horticulture, dairy, grazing and tourism. History The first European to sight the river was Lieutenant William Preston in 1831. The river was named by James Stirling, the Governor of Western Australia, in the 1830s after Admiral Sir Ross Donnelly, a friend of Stirling's father-in-law James Mangles MP. Bannister had stood in for Mangles at Stirling's wedding to Ellen Mangles. Fauna The Donnelly is one of the few catchments left in the state that contains all of the region's endemic freshwater fishes. Native freshwater species include salamanderfish (''Lepidogalaxias salamandroides''), freshwater cobbler (''Tandanus bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Western Australia
The flora of Western Australia comprises 10,551 published native vascular plant species and a further 1,131 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,317 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written details of the flora comme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvales Of Australia
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae ''sensu lato'' are known for their wood, with that of ''Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other well-k ...

Pimelea
''Pimelea'', commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and thirty six in New Zealand. Description Plants in the genus ''Pimelea'' are herbs or small shrubs usually with leaves arranged in opposite pairs. The leaves are usually paler on the lower surface and the petiole is usually very short. The flowers are usually arranged in groups on the ends of the branches and have no petals but four petal-like sepals and two stamens. The ovary has a single ovule and the fruit is usually a nut containing a single seed. Taxonomy and naming The genus ''Pimelea'' was first formally described in 1788 by Joseph Gaertner from unpublished descriptions by Joseph Banks and Daniel Solander. The first species Gaertner described was ''Pimelea laevigata'', now known as ''Pimelea prostrata''.

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Mallee Bioregion
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...

Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest.

Glabrous
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent ...
